SIGHT FOR FIREARMS.

Specification of Letters Patent.

Application filed September 27, 1913.

Patented Mar. 3, 1914.

Serial No. 792,235.

To all whom it may concern Be it known that I, FREDERICK \VILTON HANLEYPORTER, a citizen of the Dominion of Canada, residing at Quebec, in theProvince of Quebec and Dominion of Canada, have invented certain new anduseful Improvements in Sights for Firearms; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The present invention relates to improvements in sights for fire armsand has for its object to provide an efficient, compact device of asimple construction which may be folded down so as to lie flush with thesurface of the gun and which, by a very slight movement willautomatically assume the sighting position.

IVith this and other objects in view the invention consists in the noveldetails of construction and combinations of parts more fully hereinafterdescribed and particularly pointed out in the claims.

Referring to the accompanying drawing forming a part of thisspecification and in which like numerals designate like parts in all theviews: Figure 1 is a side elevational view showing the manner ofattaching my improved sight to the breech of a gun; Fig. 2 is a planview on an enlarged scale of the parts shown in Fig. 1; Fig. 3 is acentral vertical section on the line 3-3 of Fig. 2. Fig. 4% is a crosssection on the line H of Fig. 3, and Fig. 5 is a cross sectionillustrating a modified form of means for mounting the sight on thebarrel of the gun.

1 indicates the breech of the fire arm, and suitably mounted thereon isthe sight receiving member or bridge 2. This sight bridge 2 is providedwith a dovetail recess 3 for receiving the base 4 of my improved sightas will be apparent from the drawings. The said base 4, is provided withan opening or housing 5 into which the pivoted sighting member 6 may beturned down and housed flush with the base as will be clear from Figs. 2and 3. Said sighting member is further provided with the notch 7 withwhich the catch 8 engages to hold it in its depressed position. Thecatch 8 is slidingly housed in the base 4, is controlled by the spring10, and is provided With the roughened finger engaging member 11 asshown, by which it may be readily moved backward and forward in the base4.

12 represents a toe, 13 the pivot of the sight member 6, and 14 a springengaging said toe and tending normally to maintain said sighting memberin its raised or elevated position. 16 represents a set screw or othermeans for securing the base 1 in the bridge member 2.

I11 the modified form shown in Fig. 5, the bridge is extended around thebarrel to form the ring or holding means 20, otherwise the parts are thesame as in the preceding figures.

It will thus be seen that my improved sight may be readily attached toor detached from the bridge 2 by simply loosening the screw 16. I amthus enabled to readily substitute any desired sight withoutinconvenience and as the bases 1 are or may be of a standard size, suchsights will need little or no adjustment after being attached to thegun.

It is obvious that those skilled in the art may vary the details ofconstruction as well as the arrangement of parts without departing fromthe spirit of my invention, and therefore I do not wish to be limited tothe above disclosure except as may be required by the claims.

\Vhat I claim is 1. In a sight for fire arms the combination of meansfor securing the sight to the barrel provided with a recess; a readilyremovable sight base provided with a housing fitting said recess; asight member pivoted to said base adapted to enter said housing; and acatch for holding said sight member in said housing, substantially asdescribed.

2. In a sight for fire arms the combination of means provided with aslot for securing the sight to the gun; a sight base provided with ahousing secured in said slot; a sightmember pivoted to said base adaptedto enter said housing; a spring adapted to normally hold said sightmember out of said housing and a catch carried by said base adapted toengage said sight mem her and hold it in said housing, substantially asdescribed.

3. In a sight for fire arms the combination of means provided with aslot for securing the sight to the gun; a sight base spring controllingsaid catch, substantially 19 provided With a housing secured in said asdescribed.
